What Is MCEDT? The Ontario Physician Guide to EDT, GO Secure and Designees

If you're searching "MCEDT," you're almost certainly in the middle of setting up OHIP billing — and you've hit a wall of acronyms that nobody explains in one place. MCEDT, EDT, GO Secure, OPS BPS Secure, designee, MOH ID. They're related, they're not the same thing, and the order you do them in matters.

Here's the whole picture.

MCEDT in one sentence

MCEDT stands for Medical Claims Electronic Data Transfer. It is the Ministry of Health's system for exchanging claim files with physicians: you upload claim files to it, and you download your Remittance Advice, error reports, and claim rejection files from it.

That's it. MCEDT is not a billing program. It doesn't help you pick fee codes, catch errors, or track what you're owed. It's a secure file transfer channel between your practice and the ministry — the pipe, not the plumbing.

Everything you actually think of as "billing" — creating the claim, choosing the fee code and the OHIP diagnostic code, validating the health card, checking the claim before it goes out — happens in your billing software before the file reaches MCEDT. MCEDT's job starts when a properly formatted claim file exists and ends when the ministry's response file comes back.

"EDT" and "MC EDT" are the same thing. You'll see it written MCEDT, MC EDT, and just EDT depending on which ministry document you're reading. The older ministry terminology was simply "EDT" (Electronic Data Transfer); "MC" was prefixed to distinguish medical claims from other data transfer services. Same system.

The account chain: GO Secure, OPS BPS Secure, MCEDT

This is where most people get stuck, because it's three layers stacked on top of each other and the ministry has renamed parts of it over the years.

| Layer | What it is | What it does for you | |-------|-----------|---------------------| | GO Secure / OPS BPS Secure | The Ontario government's identity and login system | Your username and password. Proves you are you. | | MCEDT service | A service you enrol in using that login | Grants your identity the right to move claim files | | Your OHIP billing number | Issued by the Ministry of Health | Identifies which physician the claims belong to |

GO Secure is the older name for the government's sign-on layer; you'll now more often see OPS BPS Secure — Ontario Provider Services / Broader Public Sector Secure. Functionally it's the same role in the chain: it's the account you log into. The portal is at edt.health.gov.on.ca.

The critical point: having a login is not the same as having MCEDT access. People create the account, see a sign-in page that works, and assume they're done. You then have to enrol the MCEDT service against that account and link it to your OHIP billing number. Two steps, two systems.

One more source of confusion worth naming: ONE ID and ONE Mail are Ontario Health digital identity services used for clinical systems. They are separate from the ministry's MCEDT sign-in. If you already have a ONE ID for a hospital EMR or provincial viewer, it does not give you MCEDT access.

What you need before you can register

You can't self-serve your way into an OPS BPS Secure account from a cold start. Registration requires two identifiers that arrive in a registration letter from the Ministry of Health:

1. Your OPS BPS Registration code
2. Your OHIP Guide code

These come in the mail after your OHIP billing number is issued. If you never received the letter, or it's lost, call the ministry at 1-800-262-6524 and request it — this is a routine request and they will reissue.

The registration flow itself is straightforward once you have the codes: go to the portal, choose Register, create the account, verify your email address, select "New User," enter the two identifiers, and accept the acceptable use policy. Our step-by-step version with screenshots is in the docs: OPS BPS registration.

The prerequisite chain runs in one direction and you cannot skip a link:

CPSO independent practice certificate → OHIP billing number → ministry registration letter → OPS BPS Secure account → MCEDT enrolment → designee authorization → first submission.

If you're at the very start of that chain, read the Ontario new grad billing setup checklist first — it covers the CPSO and billing number steps in detail. This post picks up at the MCEDT end.

What an "EDT number" actually is

A lot of people search for their "EDT number" and can't find it, because there isn't a single field with that label. What people usually mean is one of these, and they're all different:

| Identifier | What it identifies | Where it comes from | |-----------|-------------------|--------------------| | OHIP billing number (provider number) | You, the physician, on every claim | Ministry of Health, after CPSO registration | | Group number | The clinic or practice group claims are paid to | Your clinic administrator, or solo setup | | Specialty code | Which specialty-restricted fee codes you can bill | Tied to your certification at registration | | MOH office code | Which ministry office processes your claims | Assigned by the ministry | | MOH ID / service user ID | Your identity inside the MCEDT service itself | Generated when you enrol in MCEDT |

All five of these appear in the header of an OHIP claim file. When your billing software asks for "your EDT credentials," it almost always wants your OPS BPS Secure login plus your OHIP billing number — not a separate standalone number.

If your claim files are rejecting at the batch level rather than the individual claim level, a mismatch in one of these header identifiers is the first place to look. Group number is the most common culprit for physicians who recently joined or left a practice.

Designees: why you almost certainly want one

A designee is a person or organization you authorize to upload claim files and download response files on your behalf, through their own MCEDT credentials, against your billing number.

Nearly every physician using billing software is using a designee arrangement, whether or not they've been told that's what it's called. Your billing platform holds the MCEDT connection; you grant it designee access to your account; it submits your claims and retrieves your Remittance Advice automatically.

The alternative is doing it manually: generate a claim file, log into the portal, upload it, wait, come back, download the response file, and load it into whatever you use to reconcile. Physicians who bill 40 patients a day do not do this by hand.

Authorizing a designee is a two-part process, and the second part is the one people miss:

1. Add the designee. In your OPS BPS Secure account, go to Designee Management → Add Designees → enter the designee's email address → Save. The system emails both parties; the designee confirms.
2. Grant permissions. This is separate. Return to Designee Management, click the designee's email address, select the MC EDT Service (Upload/Download) entry, select all the report and activity permissions, and Save.

Physicians routinely complete step 1, see a confirmation, and stop. Then on billing day their platform can't submit, because the designee exists but holds no permissions.

Two practical notes from the ministry's own guidance:

• The permissions page sometimes renders blank on the first attempt. If nothing appears after about 30 seconds, go back to the designee list and click the email address again. It usually works on the second try.
• Permission changes are not always instant. The ministry's documentation allows up to 24 hours for designee changes to take effect. In practice it's usually much faster, but plan around it rather than scheduling your first submission for ten minutes later.

Realistic timeline

| Step | Depends on | How long | |------|-----------|----------| | Ministry registration letter | Your billing number being issued | Arrives by mail after registration | | OPS BPS Secure account creation | Having both codes from the letter | Same day | | MCEDT service enrolment | The account existing | Days | | Designee added and confirmed | MCEDT enrolment | Same day, plus confirmation email round-trip | | Designee permissions active | Designee confirmed | Up to 24 hours |

Budget one to two weeks for the MCEDT portion end to end, mostly waiting on mail and email round-trips rather than processing time. The part that blows up timelines is discovering, late, that you never received the registration letter — that's a phone call and another postal wait.

What MCEDT looks like day to day, once it works

Once the connection is live, the cycle is:

1. You create claims during or after clinic.
2. Claims are batched and formatted into an OHIP claim file — fixed-width records, exact field positions, one batch header per submission.
3. The file is uploaded through MCEDT.
4. The ministry processes it and posts response files back: batch edit reports, error reports, and eventually your Remittance Advice.
5. Those files are downloaded and reconciled against what you submitted, so you can see what paid, what was adjusted, and what was rejected.

Step 5 is where the money is. A file that uploads successfully has not been paid — it's only been accepted for processing. If you're not reading your responses, you're not billing, you're mailing. Our guide to understanding your Remittance Advice covers how to read it, and reducing OHIP claim rejections covers what to do about the errors it surfaces.

Where things go wrong

Missing the monthly cutoff. Claims submitted by the 18th of the month are generally processed for payment around the 15th of the following month. An MCEDT connection that goes live on the 19th costs you a full cycle.

Designee permissions never granted. Covered above. This is the single most common "my software won't submit" cause.

Lost OPS BPS Secure credentials. Password recovery runs through the government workflow. Use "Forgot your ID or password?" at edt.health.gov.on.ca and expect it to take longer than a consumer password reset. Don't let it happen on the 17th.

Stale-dated claims. OHIP claims must generally be submitted within six months of the service date, and claims past the standard processing window are handled differently by the ministry. If your MCEDT setup dragged while you were already seeing patients, those services are aging.

Assuming upload equals payment. See above. Download and read the responses.

Where SnapBill fits

The designee step — the one that costs new physicians the most time — is automated in SnapBill. You enter your OHIP billing number and your ministry credentials, and SnapBill walks the designee authorization through the ministry portal for you: adding the designee, confirming access, and setting the upload/download permissions that people otherwise miss.

It's not instant, because the ministry side isn't instant — permission changes can take a short while to propagate after they're granted, and occasionally the ministry portal needs the permission step repeated. SnapBill handles the retry and shows you exactly which step you're on rather than leaving you guessing.

After that, the MCEDT cycle runs without you touching the portal: claims are batched and formatted, uploaded, and response files are downloaded and reconciled against your claims automatically, so your Remittance Advice arrives as a readable payment summary rather than a fixed-width file.
